Application filed 11113 14, 1925. Serial'No. 43,472.

This invention relates to sash holders such as are used on railroad car wind0ws,.but has especial reference to that class of such devices in which the operation of the lever to elevate the sash, also causes a vertically disposed plunger to be driven directly against the window sill for the purpose of releasing the sash when it adheres to such sill as by sticking. Heretofore devices of this description have been employed in which the sash was released by the action of a cam car ried by the lifting lever and operating directly against a vertically disposed plunger and the especial object of the present inven-.

tion is to develop a construction of this sort on lines somewhat different.

In the accompanying drawing which forms a part of this application Figure 1 is a broken and partly sectioned elevation showing the improvement installed on a window sash with a locking engagement effected with the metal rack at the side of the window frame.

Figure 2 is a similar view showing the position of the various parts when the lever holder and with the window casing sectioned and showing the parts in the same position as in Figure 1, and

Figure 4; is a detail perspective of the lifting lever.

Similar numerals of reference denote like parts in the several figures of the drawing.

1 is the casing of the sash holder preferably secured to the sash A by means of pins 2 driven through bosses 3 in the usual manner.

4 is the plunger pin which is vertically disposed and supported within the casing by the front edge 5 thereof and by the outer wall 6, the lower end of said plunger being contained and guided within a housing 7 which projects from the'bottom of the was ing. V

8 represents a metal rack such as is usually secured to the side of the window casing and with which the locking member ordinarily engages as will be presently seen, and the bottom of this rack is preferably extended so as to form a foot 9 upon which the bottom of the housing rests whenthe sash is close-d. This foot afiiords' a striker for the plunger pin, and avoids the necessity of providing a special striker-mortised in the window sill.

' The sash lever is denoted by the numeral 10 and is formed at its inner portion with an enlargement 11 which is'pivoted around a hollow post 12 that is cast with the casing,

a screw 13 being driven within the post outside the enlargement 11 so as to retain the operating lever in position.

The plunger at is provided on its face adjacent the enlargement 11 with rack teeth 14,, and the enlargement 11 at one portion thereof is circular and provided with gear teeth 15 which are in mesh with the teeth 14, so that it will be clear that when the lever 10 is elevated the plunger will be driven downwardly.

Extending from the enlargement 11 in the rear of the toothed portion is the ordinary lock dog 16 which is normally projected into locking engagement with the side rack 8 by a spring 17 whose ends bear against the lock casing and the heel end of the dog 16 in the usual manner.

The parts are shown in their normal position at Figure 1 and it will be observed that the bottom 'of the plunger 4: is slightly above the foot 9, so that when the lever is elevated, the locking dog will have been released from the side rack by the time the plunger has come in contact with this foot 9, so that there can be no interference in the elevation of the sash by the impact of the plunger against said foot as will be noted in Figure 2 where such elevation has been effected.

After the sash has been released by the operation of the lever 10 in the manner before described, it may be elevated in the: usual manner by lifting upward on the lever, it being, of course, understood that there are two of these constructions one at the bot- .tom of each side of the sash. After the sash has been elevated sufficiently the lever 10 is released, and the spring 17 will there- ..upon force the dog toward the rack so that it will rest on one of the teeth thereof in the usual manner, and this action of the spring will restore the lever 10 to its normal or lowered position and will thus cause the plunger 4 to be elevated to the position shown at Figure 1, so that it cannot project below the bottom of the sash and present an unsightly appearance.

The casing has extending therefrom the usual stationary lever 18 which is utilized by the operator in getting a purchase so as to exert great lifting power on the lever 10.

\Vhat is claimed I is A combined sash holder and window release comprising a casing having a pivotal post, a sash holder lever havinga hub intermediate its ends pivoted on said post said hub having teeth on its periphery and said lever having its inner end extending toqwardly from the hub to form a sash holder and having its outer end pro ect1ng outwardly from the casing. and a vertically disposed plunger in the casing having rack teeth in mesh with the teeth of the hub whereby both the upward; and downward hereto.
